The would-be prime minister has warned he will not spell out his full list of spending and cuts, but will instead wait for the pre-election economic and fiscal outlook to be released after the start of the election campaign.

Coalition frontbencher Greg Hunt has told AM that the party remains committed to delivering a modest tax cut if it wins government.

"We'll have a package of tax cuts for families without a carbon tax," he said.

The Opposition has also indicated it would keep the Government's university funding cuts and would abolish the Schoolkids bonus.
